Evening Meeting. — December IGth, 1886. 



Mr. Brooks exhibited on the screen, by aid of the oxy- 

 hydrogen lime-light, a series of photo-micrographs as lantern- 

 slides. These were Natural History subjects, and were ex- 

 plained by the President, Dr. F. Bossey, and Mr. F. G. Carey. 

 Besides the Natural History slides there were a few of general 

 subjects. 



Evening Meeting. — January 21st, 1887. 



Dr. Bossey exhibited an Elm root, 1 inch in circumference, 

 much compressed and distorted, found embedded among 

 chalk-pebbles. He also showed a section in which it was 

 clearly seen that the ducts were still sound, in spite of the 

 great compression. He called attention to a museum-specimen 

 also of the Elm, and much larger, which had been embedded 

 in chalk-flints. 



The President then read his Annual Eeport, entitled 

 ' Meteorology, Oxford Eoad, Eejjhill, 1886.' 



Barometer. — The average height of the barometer for the 

 year was 29-94 in. as observed by me. The maximum as 

 noted by mQ was 30-68 in., and occurred on November 24th. 

 The minimum was 28*47 in., on December 9th. On 178 days 

 the barometer reached 30 in. and upwards ; on 184 days, 

 29 in. and upwards ; on 3 days it fell below 29 in. There 

 was a rapid fall from 29-70 in. on October 14th, to 28-81 in. 

 on the 16th; and again from 29-84 in. on December 6th, to 

 28-47 in. on the 9th. 



During the month of January the barometer stood unusually 

 low, the average of the ufonth being only 29-67 in., while the 

 average of the year was 29-94 in. On five days only in that 

 month did it reach 30 in. December also showed a very low 

 average, 29-68 in. rising to 30 in. on six days only. On two 

 days it fell below 29 in. The average of September was 

 highest, being 30-09 in., sinking below 30 in. only on seven 

 days.
